A low pressure system will move over the state Tuesday, resulting in cooler daytime highs and partly cloudy skies.
Commuters can expect patchy fog and clouds along our coastlines and in our coastal valleys through the morning commute. By the afternoon, many of the beaches will have maximum daytime highs around the low to mid-60s. Some of our coastal valley communities will struggle to get past 70 degrees Tuesday and will mostly stay close to the mid-60s. As for the inland valley communities, daytime highs will be slightly warmer and close to the low 70s.
Northwesterly winds are making a breezy return to the forecast. Winds will range from 10-25 miles per hour, with breezier conditions increasing along the coast.
Rain chances are still in the forecast, but it's worth emphasizing that not every city will see rain. There's a 20-30% chance of rain from late Tuesday night through early Wednesday for most of San Luis Obispo County. Cities close to the south coast region in Santa Barbara County could experience light rainfall through Wednesday afternoon. Between the two counties, it's likely that rainfall amounts will be around or below a tenth of an inch.
A high surf advisory will go into effect Tuesday night until Thursday afternoon for San Luis Obispo and northern Santa Barbara Counties. During this time, surf height will range from seven to ten feet.
Looking ahead to the weekend, dry weather will be back and temperatures will trend up.
